Abbreviations: aPR, adjusted prevalence ratio; CI, confidence interval; MSM, men who have sex with men.
Among those tested via a nucleic acid amplification test at any anatomic site. Biologic testing was unavailable during the first 3 study visits that occurred during the pandemic (April 2020–June 2020).
Prevalence ratios calculated using generalized estimating equations and Poisson regression with robust standard errors to account for repeated measures among individuals and adjusting for reported value during the pre-pandemic study visit. Regression models for chlamydia and gonorrhea positivity among non-Black MSM are not shown due to small sample sizes. Bolded values are significant using P < .05.
